Study Notes
Prosthetic Terminology
- Prosthetics is the field of creating and fitting artificial replacements for missing body parts.
- Prosthesis is the artificial replacement itself.
- Prosthodontics or Prosthetic dentistry focuses on restoring oral function with artificial teeth and structures.
- Dentulous means having natural teeth present.
- Edentulous means having no natural teeth present.
- Partially Edentulous means having some natural teeth missing.
- Completely Edentulous means having all natural teeth missing.
- Complete Denture is a prosthesis replacing all teeth and supporting structures in the maxilla or mandible.
- Partial Denture is a prosthesis replacing some teeth and supporting structures, it can be fixed or removable.
- Immediate Denture is constructed before teeth are extracted and placed immediately after extraction.
Components of a Complete Denture
- Denture Base rests on the tissues and holds the artificial teeth.
- Artificial teeth are the replacement teeth.
Denture Surfaces
- Fitting surface or impression surface gets its shape from the impression taken.
- Polished surface includes the facial, lingual and palatal surfaces of the denture.
- Occlusal surface makes contact with the opposing denture.
- Denture border is the edge of the denture base where the polished surface meets the impression surface.
-
Denture Flanges are vertical extensions of the denture base from the cervical margin of the teeth to the borders of the denture.
- Buccal flange is located on the cheek side.
- Labial flange is located on the lip side.
- Lingual flange is located on the tongue side of the mandibular denture.
- Palatal portion is the part of the maxillary denture that covers the palate.
Differences between Natural and Artificial Teeth
- Forces on a segment or tooth on a denture affect the whole prosthesis, unlike natural teeth where force is localized.
- Natural teeth are better suited for non-vertical forces due to the periodontal ligament.
- Incising with natural teeth doesn't affect posterior teeth, but incising with denture teeth affects all the teeth.
- Continued bone resorption causes dentures to settle upwards and forwards, potentially causing traumatic anterior tooth contact.
Objectives of Complete Denture Construction
- Restoration of masticatory efficiency: Chewing is important for digestion and enjoyment of food.
- Restoration of facial dimensions and contours: Missing teeth cause facial changes, a well-made denture restores the natural appearance.
- Restoration of speech: Proper tooth placement allows for clear speech.
